1 Claim. (Cl. 30-53) This invention relates to safety razors in whichthe blade cutting edge is parallel to the handle of the razor.

The objects of the invention lare to construct `a safety razor in whichthe cutting edge of the blade is parallel to the handle of the razor,and which is secured in place by a readily removable cover.

in gener-a1, these objects are obtained by providing a lblade holdingsupport yattached to a handle, said support having a rib for receiving acentrally slotted safety razor blade and which rib also positions ablade cover and secures one end of the cover. The opposite end of thecover is releasably secured by a slidable collar. The blade support iscurved so that the `blade is hel-d under tension on the razor. When thecollar is retracted, the blade Will spring back into normal flatposition, and in so d-oing will push the Ablade cover off the razor,thus completely freeing the blade.

The means by which lthe objects of the invention are obtained aredisclosed more fully with respect to the accompanying drawings, inwhich:

Figure 1 is a plan view of the razor;

Figure 2 is an enlarged cross-sectional view on the line 2-2 of Figure1;

Figure 3 is an enlarged cross-sectional view on the line 3-3 of Figure1; and

Figure 4 `is ya .plan view of the yblade cover separated from the razor.

The `razor is Icomposed of a handle A which may have an extension pieceillustrated in Figure l. Handle A is formed of an upper piece 2 and -alower piece 4 'braised or welded together. Lower piece 4, adjacent theend of `the razor, has `a projecting stop shoulder 5.

Secured to the handle A, as an extension of Apiece 2, is a widenedyblade supporting member 6. This member has a concave undersurace 8, and-a corresponding convex upper surface 19. Support -6 is wider than therazor blade, being extended by a reduced flange portion 12 on yeach sidethereof containing cleaning slots 13. Flanges 12 extend under the outeredge of the razor blade to shoulders 14, thus permitting free clearancefor Ithe cutting edge of the razor blade. Axially mounted on the uppersurface 0f the support 6 is a rib 16, which longitudinally stops shortof the ends of supports 6. The support end 18 of rib 16 is undercut toform a beveled surface, whereas the rearward end 20 of rib 16 is in aflat vertical plane. Between support 6 and handle A is a slightlyattened connectng section 22, around which is a slidable metal band orcollar 24. As shown in Figure 3, this collar is formed of a strip ofspringy metal, the free ends of which are slightly spaced so that thecollar can be resiliently engaged in Ia wedging action upon a tongue aswill be described later.

Cover member 30 has a curvature of such thickness that when Vassembledon the support with blade 40, the top surface of cover 3d is flush withthe top lsurface of rib 16. Cover 3h is centrally slotted for a lengthequal to that of rib 16, and at the forward edge of the slot is abeveled surface 34, which `is complemental `to end 18 of rib 16. Therear end 36 of slot 32 is vertical to conform 'with rear end 2t) on rib16. Cover 3i) is provided with a rearwardly projecting tongue 38 whichis `slightly downwardly tapered and outwardly convergent, as shown inFigures 2 and 4. lt has a thickness such as can be tightly held byslidable collar 24, as shown in Figure 2.

in operation, assuming the razor is disassembled, an ordinary centrallyslotted double-edged safety razor blade is placed over rib 16 and isseated on :support 6. Cover 3% is then placed in position by placingslot 32 over rib 16 and sliding the cover rearwardly so that surfaces 18and 34 are lockingly engaged and end 2d is abutted by end 26. Collar 24is then slid forwardly up over tongue 33, and with a wedging actionholds cover 36 tightly in pla-ce. In so assembling the razor, the razorAblade is held under tension in a downwardly curved direction with thecutting edges of the blade extending slightly Ibeyond the longitudinaledges of cover 33. The razor is then -ready for use. When the razor isdisassembled, collar 24 is moved rearwardly, the extent of movementbeing limited `by abutment 5, and as the edge of colla-r 24 clears thetongue 38, `the tension in blade 40 will cause the blade to straightenout and `thus push cover 36 upwardly oil? the rib 16. This action isautomatic and disassembles the pieces so that they can be cleaned anddried Iand made ready for further use.

Having now described the means by which the objects of the invention4are obtained, I claim:

A safety raz-or comprising a blade support, a handle attached to saidsupport, a rib extending longitudinally of said support for positioninga centrally slotted double edge razor blade, an undercut lin the forwardend of said rib, a centrally slotted cover fitted over said rib, saidcover and support having curved blade engaging surfaces adapted to holda razor blade under tension, Ia beveled surface at one end of the slotin said cover complemental and mated to the undercut end of said rib, atongue on said Icover extending over said handle, and a collar on saidhandle slid-ably engaging said tongue.
